Abstract
The utility model discloses a water-cooled type chain grate machine fire barrier, which is formed by a stainless steel plate (1), an anchor hook (2) which is welded on the plate surface of the stainless steel plate (1), and refractory casting material layers (3), and is characterized in that an upper ring-shaped water pipe (4) is fixed on the periphery of the stainless steel plate (1), a longitudinal reinforcing rib (5) is welded on the plate surface of the stainless steel plate (1), and the refractory casting material layers (3) are respectively cast on the outer surface of the stainless steel plate (1) and the outer surface of the ring-shaped water pipe (4). Owing to embedding the ring-shaped water pipe in the fire barrier, and using the stainless steel plate as the support, the water-cooled type chain grate machine fire barrier has the advantages of firm structure, easy control of deformation temperature, free cracks and falling of the refractory casting material layers, no deformation of the fire barrier body, free burnout and prolonged service life, which can be widely applied in chain grate machine fire barriers.
Description
Technical field
The utility model relates to the improvement of the fire partition between the dry I section of a kind of chain grate machine, dry II section and the preheating section, and specifically a kind of water-cooled chain grate machine firebreak is in equipment under the hot environment applicable to chain grate machine, central cooler and all.
Technical background
Methods domestic, that produce pellet abroad have multiple, and it is one of them that chain grate machine-rotary kiln is produced oxide pellet.The effect of chain grate machine is to make green-ball progressively dry and be preheating to temperature and reach 900-1000 ℃.Chain grate machine generally is divided into three sections, and dry I section, dry II section and preheating section carry out drying and preheating by hot blast mobile.The needed flue-gas temperature of dry I section is about 250-300 ℃, and the needed flue-gas temperature of dry II section is about about 650 ℃, and the preheating section flue-gas temperature is about 900-1000 ℃.Conventional design is to separate with firebreak between three sections.At present in chain grate machine employed firebreak by heat-resisting steel sheet and plate, the anchoring hook, the heat-resisting cast bed of material constitutes, the anchoring hook is weldingly fixed on the surface of heat-resisting steel sheet and plate, on the outer surface of heat-resisting steel sheet and plate, pour into a mould the heat-resisting material feeding of watering again, as refractory layer, heat-resisting steel sheet and plate and the embedding of anchoring hook are got up, the in use existing common problem of this firebreak is: firebreak fault rate height, life-span is short, be not suitable for the high-temperature operation environment, and after breaking down, cause easily that to scurry wind between three sections of the chain grate machines serious, the Temperature Distribution imbalance, pellet quality and output all are a greater impact.
Summary of the invention
It is a kind of under the condition that does not change the chain grate machine structure that the purpose of this utility model is to provide, can improve the service life and the result of use of chain grate machine firebreak, more the high-temperature operation environment can be adapted to, the water-cooled chain grate machine firebreak of pellet quality and output can be guaranteed and improve.
For reaching above purpose, the technical scheme that the utility model adopted is: this water-cooled chain grate machine firebreak, by corrosion resistant plate, the anchoring hook, the heat-resisting cast bed of material constitutes, the anchoring hook is weldingly fixed on the plate face of corrosion resistant plate, it is characterized in that annular conduit on the periphery welding of corrosion resistant plate is fixing, also welding waling on the plate face of corrosion resistant plate, waling plays a supportive role to annular conduit with corrosion resistant plate, pour into a mould the heat-resisting cast bed of material at the outer surface of corrosion resistant plate and the outer surface of annular conduit, make annular conduit, corrosion resistant plate, waling and anchoring hook all are embedded in the heat-resisting cast bed of material.The utility model is also implemented by following measure: the water inlet pipe of described annular conduit and outlet pipe all stretch out the body of heater outside of drying grate when mounted, establish storage tank on water inlet pipe, and the volume of storage tank is 30m
3The effect of storage tank is: when water system breaks down, can guarantee normal water supply and cooling by the water in the storage tank, when avoiding breaking down suddenly because of water system, the firebreak temperature sharply raises and causes damage, the outer end of water inlet pipe to be connected with the production water supply system, and the outer end of outlet pipe is connected with the production return water system, so that water is recycling, on water inlet pipe, outlet pipe and water inlet pipe and pipeline that storage tank is connected, be equipped with valve; Described annular conduit is
108 * 8 stainless steel tube, material are Cr18Ni9Ti, and the material of corrosion resistant plate is identical with the material of stainless steel tube, and thickness is 14mm, thereby guarantee to be heated back coefficient of expansion unanimity, Stability Analysis of Structures, indeformable; The material of anchoring hook is Cr25Ni20, the spacing of anchoring hook is 150mm, becomes " W " shape to arrange, and annular conduit is bent into rectangle, its length and width all require to be advisable to adapt in the drying grate stove, the length of its corrosion resistant plate and width with annular conduit around the space consistent.
Beneficial effect of the present invention is: compare with the chain grate machine firebreak that adds heat-resisting cast bed structure by corrosion resistant plate that generally uses at present, owing in firebreak, buried annular conduit underground, can cool off by recirculated cooling water, so the temperature that has guaranteed the firebreak body is within the deformation temperature scope; Because annular conduit connects as supporting and the welding of anchoring hook with corrosion resistant plate; and annular conduit adopts identical material with corrosion resistant plate; so structure is firm; thermal coefficient of expansion is consistent; the heat-resisting cast bed of material that can guarantee the surface does not crack and comes off; thereby protection firebreak body is indeformable, do not burnt out, prolong its service life, satisfies the temperature requirement between three sections of the drying grates.
